USE
* The aggregate's standing stability is at its weakest when the load space is empty. When the ag-
gregate begins to fall, lower the grapple immediately to the ground. Do not drop the load by open-
ing the grapple.
* Make sure that there are no people in the grapple's operation area and that you can see freely
the entire operation area.
5.2
THE CRANE'S OPERATING PRINCIPLE
In order to function the crane needs a drive unit and a hydraulic pump connected to it, as well as
the necessary hydraulic equipment (such as an oil tank, filters, hydraulic pipes). All movements are
hydraulic. Different functions (turning and lifting the boom, compressing the grab, etc.) are
achieved by channelling pressurised oil with the hydraulic cylinder to the desired control valve. The
crane operator can control a number of functions simultaneously, as required.

WORKING METHOD
5.3.1 Special Safety Instructions
Never lift the load above people.
* Grab the load carefully and always as close to its centre of gravity as possible. Do not exceed the
max load indicated by the load table.
* It is not appropriate to raise loads with the telescopic boom's maximum reach, but is it better to lift
them after having drawn them closer.
* Avoid rapid lifting and lowering movements with the boom's maximum reach and turning motion
before the load is in the air.
* Do not drive the booms or swivel at the high speeds towards the end position.
* Be careful when working in the vicinity of electrical conductors. Find out the safety distances from
electric wiring and follow them. (Refer to the WARNING label).
THE MINIMUM DISTANCE FROM ELECTRIC WIRES WITH VOLTAGE > 110 KV IS 5 M.
